This invention relates to a machine for lasting different portionsof-the upper of ashoe, suc-j cess'ively, in different locations along vthehedge of the shoe bottom; in which thelasting margin of the upper issecured inlasted position, in each location, by means of- -an adhesiveand .is herein illustrated as embodied ina machine-of the type disclosedin United States-Letters Patent No. 1,796,451, issued on Marchlfl, 1931,in the name of George Goddu.- It will be understood,:however, thatin-certain aspects the invention is not limited either-to use forlasting with an adhesive'or to embodiment in .a machine organization of;the exact construction disclosed in the aforementioned'patent. I

In lasting :diflerent portions of the upper of a shoe, successively, asfor example by means of the-gripper of a machine of the type referred toabove, itis desirable-that the s Ii-Pper engage the difierentportions-of-the upper materials, hereinafter called the upper,inlocations not too widely spaced apart, in a direction lengthwise ofthe-shoe, to the :endthat substantially all portions of the upper willbe subjected to the lasting stress, applied by the gripper, andstretched snugly over the last. However, after the upper has beenstressed, in one location, and ;its,;l asting: margin secured to thebottom' of the shoe in that location, through the; action of anoverlaying member, either byanjadhesigve or-other type o-f;,fastening,for example, astaple, the lasting margin curves inga ,direction; ;lengtl1;wiseof the shoe from the. position wherexit :liesilatly against theshoe bottom to a. position where-itextends upwardly away fromv thebottom 'of.-:jthe. shoe.v Inasmuch as the gripper, afteriitphasstressedone portion ofthe upper, opens and then moves in a, direction to carrythe 'jawawhich engagesjthe inside surface of the upperdownwardlycandjoutwardly toward-the edg-eof the (shoe bottom, the shoemust'be-displaced a considerable;distance, in a lengthwise direction,inorder thatthisinnerijaw may get-in under thecurved portion of thelasting--'margin'--of the upper. Also,, if thegripper seizes-the lastingmarginof the: upper closely Ladjacent to the locatioawhereit-hasbfeenxsecured to 'th'e bottom of the, shoe; therewill be atendency for the gripper, when it" moves in a direction to tension theupper, to lift up that pornon of the upper which has just been securedtothe shoe bottom. Where the upperha's beensecured to the shoebottombymeans of a -staple, the staple may be'pulled'sout or, if securedby an adhesive, the adhesivebond may the :broken. Accordingly, inthewuseofzlasting-machines of the 25 "Claims.-

21. type disclosed in the aiorementioned'patent; i't is necessary forthe operator, who-- supports and feeds the shoe manually -to exercise a-certain: amount of care and discretionin'movingtheshoea betweensuccessive actions;- of the -gripperand overlaying member sothatdiiierent' portions oftheupper will certainly beengaged bythe gripperiandjin such locations as not todisturbportions of the upper which havepreyiouslybeen;'secured to theshoe bottom. 3

' Itiis an object of this invention to provide novel and, improved meanstor -so-Operating-the gripper of alasting machine as to makeit-possiblefor, the gripper "to jengage;-different-portions ofthelasting marginyof jthe -up1 oe'r--of{a 'shoe in closely, spacedl'ocatfrons and totensiontheuppere in thesellocati'o'ns withoutisturbingadj-aoent portions-of the upper which-"have -been -previouslysecuredin lasted position to-the'bottomoi the shoe by an overlaying menber-. Withfthis-end in view, and in accordance witha feature-of thisinvention, there is provided in a lastingfmaehina having a gripper'jandanpverlaying m mben operable in time relation, thecombination-withmechanism for, operating jfihe glippiei 130889528;

s'ioined and released one? portion oftheupper and prior to" tens'ionin,BI QthEr'portiOn of- -tl-ie upper;

More particularly, jthe arrangement is a such that the gripper may beselectively oscillated either direct-ion, lengthwise 'OfTihQfSh-bfi" androle-- tively to the overlaying member; so; that a shoe may be lasted'in either direction; from toe-'to-heel or heel to toe,,and, in,accordancewith-another ieature of the invention, thegripper-opeiatingmechanism andfth'e gripper-oscillating mesh-a nism.may-. be sojrelativelyjtimed "as to the gripper, when movingtowarda'positio line with the overlaying member, to seize a -port on oi theupper. which. is ,offset from: the-overlaying member and todisplace,thisportipn-inadirec tion lengthwise, of, the shoe and into;alipeinent with the overlaying member, prior to'its operation for.tensioning,.this,..other portion of "the" Preferably, the.glipper-operatmg 'me'chanisln is also arrangedjto. move the gripperdownwardly and laterallyof' the shoe',',injtime relationto the action ofthe gripper-oscillatingmechanism! Be cause ,of the.,movements which areimpartedto thegripper by the actions of thegrippenoperate;

3 7 ing and the gripper-oscillating mechanims, when the shoe isdisplaced in a lengthwise direction to present another portion of theupper to the actions of the gripper and the overlaying member, the jawof the gripper which engages the inner surface of the upper is firstadvanced toward the upper in a location where the upper extends awayfrom the shoe bottom and is then moved in a direction lengthwise of theshoe and 1 toward a positioon substantially in line with the overlayingmember, before the gripper is operated to seize and tension this otherportion of the upper. Thus the gripper jaw is readily inserted beneaththe lasting margin of the upper closely adjacent to a location wherethelasting margin has been secured to the shoe bottom. Also, by causingthe gripper to seize a portion of the upper which is ofiset from theoverlaying member and to displace this portion in a direction lengthwiseof the shoe, a certain amount of fullness is placed in that portion. ofthe lasting margin between the gripper and the location where the upperhas been secured to the shoebottom.. Hence, when the gripper is operatedto tension another portion of the upper, this fullness which has beenplaced in the upper tendsto prevent the stress applied by the gripperfrom lifting the lasting margin of the upper which has been previouslysecured to the shoe bottom. 7

- Although the aforementioned advantages of the [DOVE]. and improvedgripper-operating mechanism may be obtained when the shoe is manuallyfed alongby the operator, by increments of a magnitude such as to causethe gripper and overlaying member to operate, successively, on closelyspaced portions of the upper, in accordance with another feature of theinvention, means are provided for intermittently'feeding the shoe topresent laying member. Preferably, and asherein illustrated, thisfeeding means comprises a feed wheel wise of the shoe. ,g

Another object of thisinvention is to provide a noveloverlaying memberand improved means for operating the overlaying member, in time relationto the updraw and overdrawactions of the gripper. To this end, theoverlaying member is arranged to move along a path that is inclineddownwardly toward the bottom of a shoe presented-to'the machine and isprovided with an operating surface that isv disposed at an angle to itspath of movement and substantially parallel to the bottom of the shoe,while the operating mechanism is arranged to cause the overlaying memberfirst to move toward the shoe bottom, during a portion of the gripper,then to pause while the updrawing action is completed and finally tocontinue'itsmovement during the overdraw so as to lay the lasting marginof the upper in over, against, the bottom of the shoe just as the upperdifierent portions of the upper to the actions of the gripper and theover-,

seized another portion of the upper and is displacing it in a directionlength- 1 updrawing action of the and to press it is released by thegripper. With this novel overlaying member construction, the lastingmargin of the upper is laid flatly against the bottom of the shoe whilethe improved action of the means for operating the overlaying member notonly insures that the updraw action of the gripper will be completedbefore the overlaying member engages the upper but also makes certainthat the overlaying member will engage, and follow, the upper during theoverdrawing action of the gripper so as to be in a position to press thelasting margain against the shoe bottom at the instant it is released bythe gripper.

When lastingwith an adhesive, it is necessary that the lasting margin bepressed firmly against the bottom of the shoe with a considerable forceto insure that the lasting margin of the tensioned upper will besecurely bonded to the shoe bottom. It is also desirable that thisbonding pressure be applied to the entire lengthwise extent of thelasting margin without any gaps between locations where pressure isapplied. Accordingly, and in accordance with another feature of theinvention, the overlaying member is provided with a hammer which isadapted to strike the operating surface of the overlaying member and Iis so mounted as to be self leveling to strike the lasting marginsquarely and evenly, regardless of lengthwise and widthwise curvaturesof the shoe bottom. Also, to the end that all portions of the lastingmargin be subjected to the pressure of the overlaying member and/or thehammer, the feeding means is so constructed and arranged as to impartfeeding movements to the shoe of .a linear extent that is less'than thewidth of the areas to which pressure is applied.

Referring. to the drawings and particularly Figs. -1 and 2 thereof, thefeatures of this inven-' tion are illustrated as embodied in amachineofthe same general construction asthat shown-in the aforementionedpatent. Thismachine hasa gripper, comprising. jaws 30, 32, an overlying;

member, indicated. generally by thereference character 34, ashoe-bottom-engaging feed wheel 36,. and an edgegage roll 38.Theseiseveral operating elements are associated. with; and operated by,mechanism containedrwithima hollow" head construction 40.which.ismounte'don-the top of a column 42'of suitable height. The var--ions-operating mechanisms are driven from cams carried by a main shaft44whichis drivenfrom a power' source not shown, .by meansioft a: clutchmechanism similar to that provided in the machine of the mentionedpatent, andrunder the. control of two-treadle rods 46 and48;.corresponding respectively to the two treadle rods I26 and I84 ofthe patented machine.

Turning now to Figs. 1, 2, 6, 7, 13 and 14, the" gripper is of thesameconstructionas that of.

the prior patent and is suspended-fromatwo:

part updrawing lever-50, mounted on the head 40, b-y means ofa pivot pin52, Fig. l3,- and. its. body portion 54 is slidablymounted in a member56 that is threaded to receive a screw 58. Fig. 14; for. a purpose to beexplained below. The screw: 58 is .rotatably supported, at its-oppositeends,in a bracket member 60'. and .an extension 62v secured thereto, andthis bracket member is formed integrally with an overdraw rod-64, whichcor.- responds to the overdraw rod 2H] of the patented machine and isconnectedto atwo-piece overdr'aw lever 5'6iby means of a pin 68 andblockT0,".Fig. 7." Carried by the. updraw lever 50 is .a gripper-closing rod'72 'which, at certain times-inthe operating cycle of the machine,closes. the. jaws30, 32"'ag ainst'the resistanceofia jaw-openingspring14; 1L

The gripper ofthe herein illustrated. machine: is'operated in the samemanner for seizing, up,- drawing, overdrawing and releasing different.portions of the upper of a shoe as thegripper. disclosed and describedin the aforementioned patent, the. gripper-closing rod.112-,' updrawlever 5'02 overdr'aw rod'6'4 'andgrippereopening. spring ll-being underthe controlof'various operating camsgnot shown, carried by the-mainshaft 44 Also; the updraw action and overdraw: action 1 impartedto'the-gripperjaws 30, 32. by' the updraw lever '50 and the overdrawrod-64 may be varied, respectively, by a hand nut-16 and a handlever 'lllinth'e'same-manner and .by mechanisms similar to those disclosed in theaforementioned patent to which reference may be made for a detaileddescription of'these-various gripper-operating' mechanisms which form-nopart of the present invention.

Referring again to the screw-58,- which'is received'by the member 56, inwhich the bodypor tion *54 of the gripper' is-mounted, this screw isadapted; when" rotated, to impart additional movements tothe gripperjaws 30, 32,- for the purpose of certain features of-this invention. Inv

the operation of the gripper-operatingmechanism which has been so fardescribed, and as set forth in the prior patent, after the gripper hastensioned a portion of the upper of ashoe, the

jaws 30-} 32 are first opened, next moved-down wardly to positionthe'inner jaw-30 close to the bottom of the shoe, and then the gripperismoved laterally of the shoe to shift the inner jaw 30-; outwardly to theedge of the shoe'bottom and into a position to engage the inside'surfaceof theupper material when the jaws are again closed. In addition tothese movements of the gripper, which take place in a vertical. planesubstantially in line with the *overlayingmember-M; the gripper jaws 3032 are'oscillated in adirectionlengthwise of the shoe; first awayfromand'then toward a position in line: with the overlaying. member; inthe following manner.

The screw 58: has. formedthereona-pinion 89 which meshes; with a rack 82that: is-- slidably mounted: in the. bracket member 60- and-connected;by means of a link 84, to an arm 86; Fig. 6.

This armis pivoted'on. a stud 88-,-carried by an upstanding portion 99:of the-head 40: and has two oppositely extending ears 92,- 94, to whi rIlll, that is mounted on a stud. I I2 carried by a downwardlyextendingportion. H4 on the head 40. A pin H6 extends through theelongated slots in the ends. of the links 96 and 98 and this pin'ismounted in the bifurcated end. of the arm I03.

The arm llil of. the bell-crank lever carries a cam roll [39,. which.engages a cam III on the main shaft 44 (Fig. .9) and this cam is soshaped that the bell-cranklever is rocked, once for each revolution ofthe mainshaft, first down to the position shown in Fig.6 and then up inthedirection of the arrow. When the two links 96 and 98 are moveddownwardly and to the positions shown in Fig. 6; the pin Il6'"will'eng'ag'e the elf-'- set portionl 02 of the slot [00in thelink96, while at the same timesliding freely along the slot I04 inthe link98, so that the link 9'6'Will be reciprocated'in such a manner as tocause the arm.86 to oscillate, down from the dotted line: position-tovthe solid line position shown inFig. Band then back to the dotted-lineposition. On" the other hand; when the links 95, 98f'are moved upwardly,the pin I It" will engage the onset por= tion I of the slot I04 in thelink 98 (see Fig. 8), while sliding freely along the slot I00 in thelink 96, so that the link 98 will be reciprocated in such a manner as tocause the arm- 86 to oscillate upwardly from, and back to, the dottedline position shown in Fig. 6. When the links 96 and 98 are moveddownwardly, to the position shown in 1 Fig. 6, the screw 53 will berotated back and forth, through the actions of the rack 82 and thepinion B0, in such a manner as to cause the body portion 54 of thegripper to be swung about the axis of pin 52, Fig. 13, in a directionfirst to carry the jaws 30, 32 to the right, solid arrow in Fig.

14, away from a mid-position in which th jaws following mechanism isprovided, rods I20, I22

are pivoted, respectively, to the links 96 and 9B,

and each of these rods passes through an opening I24 formed in a blockI26 that is carried by a hand lever I28, Fig. 6. For the purpose ofsimplicity, and since the lower end of the rearmost rod I22 issubstantially hidden behind the lower end of the front rod I20, only thelower 'end of the latter is shown in the drawings. On each of these tworods there are a pair of collars I30 and I32 between which and the blockI29 are mounted compression springs I35, I35. A tension spring I38 isstretched between the block I26 and a lip I40, supported on stud I I2,and the arrangement is such that the spring I33 acts as a toggle springfor holding the hand lever in either position to which it may beshifted, either to elevate or to lower the links 96 and 98, through theactions of springs I34, I35. Thus, by manipulating the lever I28, thegripper jaws 30, 32 may be selectively oscillated in either directionlengthwise of the shoe first away from and then toward a position inline with the overlaying member. This oscillation of the gripper jaws30, 32 in a direction lengthwise of the shoe is effected in a definitetime relation to the operation of the gripper jaws to seize, updraw,overdraw and release a portion of the lasting margin of a shoe as willbe more particularly explained below.

The overlaying member 34 is mounted for sliding movement on a guideblock I50 which is se' cured to an arm I52, formed integrally with atrunnion shaft I54, Figs. 3 and 15. This trunnion shaft is journaled ina portion of the head 40 and has a reduced end portion I56 to whichthere is keyed an arm I58. This arm carries two adjusting screws I53,I92 which are adapted to bear against a stud I64, screwed to the head40. By manipulating these screws, the guide block I may be tilted,relatively to the head 40, so as to vary the angularity of the path ofmovement of the overlaying member with relation to the bottom of a shoepresented to the machine. The overlaying member 34 is reciprocated onthe guide block I50 and along a path inclined downwardly toward thebottom of the shoe, in time relation to the action of the gripper bymeans of a cam I'IO on the main shaft 44 which engages a cam roll I12,carried by the overlaying member, see Fig. 9. The path of this cam isshaped with two risers I'Il, I13, so that th overlaying member is movedtoward the shoe bottom in two distinct steps.

For laying the lasting margin of the tensioned upper in over, and forpressing it against, the bottom of a shoe, the overlaying member isprovided with an operating surface I80, having a nose I8I. which isdisposed at an angle to the path of movement of the overlaying memberand in a plane that is substantially parallel to the bottom of a shoepresented to the machine, Figs. 3, 9, 17, 18 and 19. As shown in Fig.19, when the overlaying member 34 is moved along its inclined path bythe cam I10, the operating surface I will lay the lasting margin of theupper over, and press it flatly against, the bottom of the shoe. Inorder to augment the pressing action of the overlaying member, it isprovided with a hammer I82 which is arranged to project through anopening I85 in the operating surface I80 and to strike the lastingmargin of the upper a sharp blow after the lasting margin has been laidin over, and pressed against the shoe bottom, by the operating surfaceI39.

This hammer is carried at the lower end of a plunger I84 which isslidably mounted in the front end of the overlaying member 34, Figs. 3and 9. At its upper end, this plunger is connected to an operating linkI86 which is pivoted to a bell-crank lever I88, carrying a roll I92 thatis held against a cam I92 by means of a spring I94, see Fig. 9. The camI92 is mounted on the main shaft 44 and is so shaped that the plungerI84 will be projected downwardly by the spring'l94, to cause the hammerI82 to strike the lasting margin a sharp blow, at the termination of theoutward and downward movement of the overlaying member by the cam I19.An adjustable stop I93 is arranged so as to engage a bumper block I95,carried by the overlaying member, for limiting downward movement of theplunger I04. The hammer I82 is provided with an operating face having aplurality of projections I98, Fig. 5, so as to concentrate its actionover a plurality of closely spaced points on the lasting margin and ismounted so as to be self leveling in the following manner. The lower endof the plunger I84 has a spherical recess I and the hammer isspherically shaped at 200 so as to be held in this recess by means of aspring 202, Figs. 3 and 19.

The shoe-bottom rest of the machine comprises a feed wheel 35 which isoperated to move the shoe along in time relation to the actions of thegripper and overlaying member in the following manner (Figs. 1, 2, 3, 9and 10). The feed wheel is formed integrally on the end of a shaft 298that is journaled in the lower part of a forwardly and downwardlyextending bracket 300 forming part of the head 40 (Figs. 3 and 1G) Onthe shaft 298 is a bevel gear 392 which meshes with a bevel gear 394carried by a shaft 353 that extends upwardly in the bracket 300. Theshaft 306 is provided with a portion 303 of enlarged diameter which isreceived in a counterbore 389, formed in the bracket, and beyond theenlarged portion 308 there is pinned to the shaft 398 an elongated hub3I0 which comprises part of a double-faced ratchet wheel 3I2, Fig. 10.Slidably mounted on the hub 3H) and on an extension 3 of the shaft 306is a cage 3I5 c0mpris 111g end plates BIB, 320 and a cylindricalintermedlate member 322, secured together by means of screws 324, Fig.10. The end plate 320 has extending therefrom a shaft 326 which is jo Iracks ;-,nru eans-ofv a plate 358. theaahm 356 is an extension carryingaroll 360 that engages a earn 362 carried by the main shaft -naledin thebracket. 300 and-bored .to .receive ntherend 31,4. of the-shaft 306.

.Beferringto Figs. and 11, there is-secured tothe end plate: 318 a sheetmetal disc 328 which is cutaway. so as to providethree outwardlyprojecting spring fingers330. 1 The lower face of .theratchet wheel 312isformed with a series, of teeth 332 that are faced in a directionopposite .to the fingers 330. Similarly, there issecured tothe end plate.320 a disc 334 that is formed rwith three spring fingers 336 and-theupperface 7,01 the ratchet wheel 3|2.isprovided with a series of. teeth.338 that face in a direction opposite :tOithQ fingers 336 and alsoopposite to the-teeth .332. Thevshaft; 326 is formed with a pinion 346 twhich. is adapted to mesh with either one of two racks 342 or 344.

The mode-of operation of the, several elements of the machine will nowbe explained with referber 34, 5110515 .fed along intermittently, by thefeed ,ence to the lasting of a shoe comprising an upper U and lining Lassembled on a last A together with aninn'er sole I.

Referring particularly to Figs. 3, 4, 16, 17, 18,

19 and 20, the operation of the machine will be outlined in the mannerin which it occurs when the hand lever I28 is moved to the positionjmove to. the right and then return to their midposition in alinementwith the overlaying mem- In Fig. 16, the direction in which the wheel,is indicated by .a solid arrow and the movements of the gripper jaws arediagrammaticallyillustrated by means of a relatively heavy arrowed linea, b, c, d, e, and 1, that corresponds roughly to the path of movementof the inner jaw 30. Similarly, in Fig. 4, the arrowed line a, c, d, and1 represents the path of movement of the inner jaw 38 in a horizontalplane, while in Figs. 17 and 18 the arrows showing the direction ofmovement of the gripper jaws are identified with the letters e and fcorresponding to similar portions of the arrowed line a to f.

It has already been pointed out above that the actions of the gripperjaws 39, 32 to seize, updraw, overdraw and release different portions ofthe upper materials of a shoe are the same as those of the gripper ofthe machine disclosed in the above-mentioned patent. The overlayingmember 34 also operates in timed relation to the tensioning action ofthe gripper substantially in t the same manner as in the patentedmachine. However, in the herein illustrated machine, the gripper jawsare also oscillated in a direction lengthwise of the shoe, first awayfrom and then toward a position in line with the overlaying member andthe shoe is fed along, intermittently,

, by means of the feed wheel in time relation to the actions of thegripper and the overlaying member; i

Referring now to Figs. 3, 4, and 16-20, a complete operating cycle willbe described beginning at about 240 on the timing chart (Fig. 20) Atthis point in the cycle, the gripper jaws 3D, 32 have just tensioned andreleased a portion of the upper materials U and L and the lasting 1margin has been secured in lasted position to the inner sole I, by meansof an adhesive coating previously applied to the inside surface of theupper materials and/or the insole, as a result of the pressing actionsof the overlaying member 34' and the hammer [82, see Fig. 19. The hammerl82 has been elevated to a slight extent (see hammer cam on timingchart) in order not to interfere with the feeding of the shoe whichbegins immediately, the feed wheel 36 being rotated in a direction tomove the shoe to the left in Fig. 16 (see feed cam on timing chart).During the time that the shoe is thus being moved to the left, theoverlaying member 34'is withdrawn away from the shoe bottom and thegripper is swung to the right by the screw 58, so as to cause the innerjaw 30 to move along a path indicated by the line a (pincer side throwcam). At the conclusion of the feeding movement of the shoe and whilethe shoe is being held stationary by the feed wheel 36,

the'gripper first descends and causes the jaw 30 to move along the linebitoward the inner sole I (updraw cam) and then moves outwardly to causethe jaw 30 to follow the' path 0 (overdraw cam). Now the gripper isreturned to its mid-position in alinement with the overlaying member 34,see liner-41: in Fig. 4, so that the jaw 30 followsthe path at (pincerside throw cam).

As shown in Fig. 16 by the broken lines, the lasting margin of the uppermaterials curves upwardly and outwardly, from the location where it hasbeen secured to the inner sole, indicated by the dotted linerepresentation h of the area acted on by the hammer in Figs, 4 and 16,to a position where it is nearly vertical tothe inner sole. By movingthe gripper jawsin directions lengthwise and heightwise of the shoe andcausing the inner jaw 35 to follow substantially the paths a, b, c, andd, this jaw is easily inserted beneath the lasting margin of the uppermaterials, in a location closely adjacent to the place where the upperhas been secured to the inner sole, sinceit first moves toward thelasting margin in a location where the margin is merely vertical andthen moves in'a direction lengthwise of the shoe'beneath the margin. Aswill be apparent from an examination of the timing chart, Fig. 20, thecams are so shaped that the path a to d is only approximated andmovements along the pathsb, c, d occur simultaneously and more or lessalong the arrowed line b, c, d, Fig. 16. However, the inner jaw isinserted beneath the curved portion of the'lasting margin before thegripper has returned to its mid-position and prior to operation of thegripper to seize, tension and release another portion of the uppermaterials.

After the gripper has been returned to its midposition and the inner jawinserted beneath the lasting margin in the manner explained above, thejaws 38, 32 may be closed to seize the upper materials, as shown in Fig.17. Next, the gripper jaws are moved upwardly substantially along thepath e to exert an updrawing stress on the upper U and lining L fortensioning these materials over the last A. Preferably, and in theherein illustrated machine, the inner jaw 30 is provided with a smoothoperating face 503, for engaging the lining L, while the outer jaw 32has a toothed operating surface 502 for engaging the upper U, and thejaws are closed on the upper materials with a relatively light pressure.Accordingly, as the jaws 30, 32 move upwardly, along the path e, theupper and lining slip through the jaws, the tension in force applied bythe smooth jaw 30 being just suflicient to remove any looseness from thelining, and the greater tensioning force exerted by the toothed.

jaw 32 being sufficient to stretch the upper snugly over the last A. Atthe conclusion of this upward movement of the jaws 39, 32, the variousparts assume the positions shown in Fig. 18. Thereafter, the jaws aremoved along the path f to draw the lasting margin inwardly over theinner sole and, at the conclusion of this overdraw movement, the jawsare opened to release the upper materials which are immediately laid inover, and pressed against, the inner sole by the actions of theoperating surface Hill on the overlaying member 34 and the hammer I82.

As explained above, the overlaying member 34 is moved toward the bottomof the shoe along an inclined path, see arrows Figs. 1'? and 18, and inaxthe movement. of: the: 'overlayingrmember: occurs during the.beginning of the upward movement ofthe-jaws 30, 32, in the direction ofthe arrow .fe; Fig. 17, and thearrangementis such that --movement :orthe-overlayingmemberv is-;.arr.ested I and the overlaying memberheldstationary while the upward. movement of "the j aws .is completed,the. overlaying member stopping withjitsnose IBI i 'justi touching thetension :lasting ,marginflof the upper materials .as shown in Fig. '18.Now,- as

the jaws are moved to the left, in the direction of the arrow f, todraw'the lastingmargin of: the tensionedupper materials inwardlyworerthe inner sole I,- the second :step of the-movement of the overlayingmember occurs so that theover laying member follows the .inwardmovement:lof the lasting margin and finally lays the lasting 1' marginin over,and pressesitflatly againstgthe .sinner sole I, Fig. 19; with aneasyxand .smooth raction which :does not'jar the shoe, just ,af-terthe'J'aws'are opened -(approx.;195 on'the, timin .rchart, Fig. 20). Thehammerv I82 isinow operatedto strike the lastingmargin of ftheuppermaterials a sharp blow, to cause :the .lasting margin to. be securelybonded to the inner sole by. the previously applied adhesive, at about.210" on the timing chart. The cycle. is completed in the-next:30during'whichthe hammer is elevated prior to the withdrawal of theoverlaying member which occurs at the beg n g'ofthenext cycle .asexplained. above.

.Asrsuggested above,:" it is desirable :thatfthe gripper jaws '30, 32.operateon closelyispaced portions of the upper materialsto the end-thatjthese materialszmay be snugly. stretched over thelast.:It'istalso-important. thatiall; portions of thelasting :margin besubjected to the action of-the -.hammer;so that every lengthwise partofrthe'last- -ring-margin.will bev securelybonded to the inner -ssole.bythe adhesive. ..Accordingly; the feeding v:incrementswhich are impartedto the shoe byxthe .feedwheel 36 preferablyshould be at least of nogreater. linear extent thanjthe 'widthof the operaitiveface. of thehammer 1.82. v.Referringuto Figs.

.-In orderto avoid this difilculty, whileistill .re- :taining theadvantages of the relatively short feeding, increments, the followingarrangementris provided. Referringyto Fig. 4 and Fig. 20, the

;jaw.;cam.is so shaped as toeffect. closing of the laws 30, 32 on thelasting margin before the jaws have returned all the way to theirmid-position. 15...

At this time in the cycle, the shoe is held stationary. against movementin the direction of feed bythe feed wheel 36 and the. action of :thespring .fingers 346 (Figs. 10 and 12.) so that as the jaws completetheir return movement a certain amount of fullness y,is placed in thatpart ,of the lasting margin which is between the gripper jaws and thelocation where the lasting margin is secured to the inner sole, see Fig.4. Now, when the jaws are operated to updraw the upper materials, thisslight fullness to a considerable extent isolates that portion of thelasting margin which has been secured to the inner sole from thatportion which is being tensioned and, in this manner, prevents theformer from being lifted up or otherwise disturbed. It has been foundthat a very slight amount of fullness is quite effective, in thisrespect, and, in fact, if the jaws are closed in a location only 1%" to4 away from mid-position,.as

'- shown on the timing chart, alldifllculties with regard to adisturbance-of previously secured portions of-the lasting margin isavoided. At the same time, sucha small amount of fullness is tion offeed, results in a better lasting action.

With-the updraw' and pincer side throw: cams shaped, :as illustrated onthe timing chart, Fig. 20,

:the updraw movementofthe'gripper begins while 1 the gripper isreturning to its mid-position. However, no actual tension is applied tothe upper materials until the gripper jaws have returned to mid-positionand :the aforementioned fullness placed in :the 1 lasting margin of theuppermaterials.

In'lasting'a shoe,'it is a usual practice for the -operator to start'the lasting operation at the breast line, on one side ofthe shoe, andthen to proceed to the tip line. After'one side of the shoe has sheenlasted; the-shoe is turned around to bring its other side tothe'machineand the lasting :operationrepeated; again beginning at the breast lineand proceeding to the tip line. Obviously,

such a procedure requires that the shoe be fed along from right to left,on one side, and from left to right on the other side. -In the hereinillus trated machine, the direction of feed maybe re- 'versed byman-ipu-lating the hand'lever I28 which also changes :the direction inwhich the gripper jaws 30, 32 are moved away from theirmid-position. Thedotted-arrow on the shoe and the relatively light arrowed line a to d inFig. 16in- :clicate the direction' of'feecl and the" path of :movementof the-gripper'when the hand lever 28 is moved to the position shownindotted line in Fig; 6 and :in'solid line in 'Fig. 1. It will beunderstood that the portions e and f of the'path of movement of theinner jaw 30'will be the same,

and-lie in a plane :t-hatis in .alinement with the overlaying member 34,regardless of the position of the hand lever I28.

As suggested above, the operation of the main shaft it is under thecontrol of two treadle rods so and 4B. In the same manner as in theprior patented machine, these treadle rods are arranged to be operatedby two treadles, not shown, in such a manner that both rods may be moveddownwardly to effect operation of the gripper, feed wheel and overlayingmember, or the rod 4-5 only may be moved downwardly to efiect operationof the overlaying member and feed wheel, while the gripper remains idle.In either case, the clutch mechanisms are adapted to present the mainshaft to a stop with the gripper jaws opened and the overlaying memberwithdrawn,

as shown in Fig. 3. Also, the feed wheel 36 may be disconnected from itsdriving means should the operator wish to feed the shoe manually.

. Under these conditions, the hand lever I28 may still be manipulated tocontrol the widthwise movement of the gripper jaws in accordance with 1edirection in which the operator desires to feed the shoe.
